title: [A case of papillary cystadenocarcinoma of the prostate].
abstract: An 86-year-old was admitted to our hospital with the complaint of urinary retension. Ultrasonography and CT scan revealed a large cystic intrapelvic mass which was palpated on the bilateral inguinal portion. When the needle aspiration was performed, we aspirated serous fluid which a concentration of prostate-specific antigen (PSA) was remarkably elevated to 6200 ng/ml. Following hormonal therapy with diethylstilbestrol diphosphate, maximum androgen blockade with Flutaminde and LH-RH analog was performed. But no reduction in the size of the cyst was observed, he died from dyspnea caused by carcinomatosa 91 days later. Autopsy revealed a papillary cystadenocarcinoma of the prostate. Furthermore, we revealed that the cyst is primary and neoplastic changes supervened in this case. Seven cases of papillary cystadenocarcinoma of the prostate in the Japanese literature are reviewed briefly.
